CD and DVD are fragile media that can be scratched at any time. I will share with you how to recover important data from these damaged discs.First, we will analyze the damage caused by scratches on the disc.

Try to repair damaged disk

If your disc has deep scratches, you can repair it. The best way to do this is to use white toothpaste or medical gel (preferably on an optical instrument). Of course, you can also use BRASSO.

 

First, use a soft cloth to wipe the disc surface. If there is oil stains, you can use a mild detergent for cleaning. Make sure there are no fingerprints or other pollutants on the disc. During cleaning, do not use too much force to avoid injury.

Use toothpaste or lotion to apply to the damaged part of the disc surface. In the beginning, please try to control the amount to prevent excessive pollution to other parts, and then gently wipe it out from the center with a soft cloth.

Of course, not all disks can be recovered. Sometimes, only part of data can be recovered for some disks.
